I have a localhost node.js web server that contains 1MB of data

And a client which I'm trying to download the data from using require('http')

after 130 iterations the program breaks:

Error: connect ECONNREFUSED 127.0.0.1:3000

Here is my code:

const timeWrapper = (callback, param) => {
    const start = performance.now();
    callback(param)
    const stop = performance.now();
    console.log('Runtime: ', (stop - start)/1000 + ' seconds');
}


const getData = (from) => {
    for (let i = 0; i < 1000; i++) {
        download(from);
    }
}

// Don't work
timeWrapper(getData, web);

I'd like to know how to fix it
